This issue of JCOM explores the question ‘what works in science communication?’ from a variety of angles, as well as focusing on the politically sensitive topic of climate change. In addition, the issue contains a set of commentaries that explore the sometimes conflicting roles of universities in science communication.

The four essays in this Commentary examine contributions of universities to science communication's development but also challenges in consolidating those efforts.

This paper reviews the purposes, definitions and criteria designed to embed ‘engaged research’ as a strategic priority with universities, and explores some of the challenges of implementation. Surveys of academics have shown various understandings of, and attitudes to, the practices of engaged research, but also impediments to realising the aspirations it expresses. Drawing on the experience as the academic lead for engaged research at the Open University, the author explores questions of professionalisation, for example, through training, support mechanisms and measures of recognition for engaged research. He concludes by arguing that, if done well, engaged research can promote epistemic justice.

This essay examines several distinct roles universities play in science communication, with particular reference to professionalisation in the field. It identifies the ways in which universities have facilitated, even driven, that continuing process. But it also notes the potential and actual contradictions between some of the roles of universities, reflecting current developments in higher education across many different contexts.

The National Autonomous University of Mexico (UNAM) is one of the world's single largest employers of science communicators, with over 350,000 students and 40,000 staff. Its science communication activities include five museums (Universum, Museo de la Luz, the Geology Museum, Museo de la Medicina Mexicana and Musem of Geophysics), botanical gardens, as well as a wide range of cultural and outreach activities. It has several programmes for training professional science communicators. The science communication staff are spread across the campuses in Mexico City and four other cities, including writers, explainers, researchers, evaluators, who produce exhibitions, magazines, books, theatre, screenings and science cafés. This activity is diverse and sometimes operates to different agendas.

This article aims to present a critical analysis of the book entitled “Creative Research Communication ― Theory and Practice”, written by Clare Wilkinson and Emma Weitkamp (Manchester University Press, 2016). We aim to present the structure of the book, highlighting its strengths and successes. Although some chapters focus on the UK, the book offers a wide range of examples of practical activities for the communication of research of global interest and provides very useful tips. Ethical issues and the importance of evaluation, of how to do carry out such evaluation and dissemination, are also presented in an inspiring way. Well-written and objective, the book is a must-read for anyone who works, or aspires to work, in the field of public engagement with research.

This study explored how different presentations of an object in deep space affect understanding, engagement, and aesthetic appreciation. A total of n = 2,502 respondents to an online survey were randomly assigned to one of 11 versions of Cassiopeia A, comprising 6 images and 5 videos ranging from 3s to approximately 1min. Participants responded to intial items regarding what the image looked like, the aesthetic appeal of the image, perceptions of understanding, and how much the participant wanted to learn more. After the image was identified, participants indicated the extent to which the label increased understanding and how well the image represented the object. A final item asked for questions about the image for an atronomer. Results suggest that alternative types of images can and should be used, provided they are accompanied by explanations. Qualitative data indicated that explanations should include information about colors used, size, scale, and location of the object. The results are discussed in terms of science communication to the public in the face of increasing use of technology.

Shroeder Sorensen analyses in depth the close relationship of the TV-series Cosmos [1980] with the popular culture, in its broadest sense, at the time of its release. The novel application of Fantasy-Theme analysis to the rhetorical vision of the series reveals how it is the product of a very careful and successful design. The book also compares the original series with its 2014 reboot Cosmos: A Spacetime Odyssey [2014].

Marked by the diversity of initiatives linking science and art and by new presentation formats, the 15th Congress of the Network for Popularisation of Science and Technology in Latin America and the Caribbean (RedPOP) saw heated debates on science, culture, politics and society. Between 21st and 25th August, it brought together in Buenos Aires (Argentina) about 400 participants from 14 countries in order to share new visions, initiatives and research work in science communication. During the event, which included a vast cultural programme, a series of challenges were raised for the future development of the field.

Research suggests non-experts associate different content with the terms “global warming” and “climate change.” We test this claim with Twitter content using supervised learning software to categorize tweets by topic and explore differences between content using “global warming” and “climate change” between 1 January 2012 and 31 March 2014. Twitter data were combined with temperature records to observe the extent to which temperature was associated with Twitter discussions. We then used two case studies to examine the relationship between extreme temperature events and Twitter content. Our findings underscore the importance of considering climate change communication on social media.
